A space registration system includes a display apparatus, an image sensor, a processor, and a plane mirror. The display apparatus has an inherent display coordinate system which defines a coordinate of the virtual space. The image sensor has an inherent sensor coordinate system which defines a coordinate of the real space. The processor analogizes a transformation equation of the sensor coordinate system and the display coordinate system by means of symmetry of an incidence angle and a reflection angle of light with respect to the mirror surface, compares a coordinate of the reflection image with respect to the display coordinate system with a known coordinate of the reflection image with respect to the sensor coordinate system, and adjusts the transformation equation of the sensor coordinate system and the display coordinate system.

An apparatus and method for simultaneous transmission scheduling in a multi-hop cellular system are provided, in which a base station presets simultaneous transmission relay station set information and transmits the simultaneous transmission relay station set information to relay stations managed by the base station, and an relay station receives the simultaneous transmission relay station set information from the base station, determines, upon receipt of a data frame from the base station, a state of the relay station preset in relation to a receiving relay station for the data frame by comparing an ID of the receiving relay station included in the data frame with the simultaneous transmission relay station set information, and operates according to the preset state.

A method for receiving multicast service data by a terminal in a communication system. The method includes receiving a pilot from a base station, measuring channel state information using the received pilot, and transmitting the channel state information to the base station; receiving a frame from the base station, and determining whether there is an error in the received frame; when no error has occurred in the received frame, determining whether the number of frames consecutively received without error is greater than or equal to a predetermined number; and when the number of frames consecutively received without error is greater than or equal to the predetermined number, transitioning to a non-feedback state where the terminal transmits no channel state information to the base station. The frame includes multicast service data.

An apparatus is invented for implementing adaptive routing in packet switched networks. The hardware structure of the apparatus is based on the AntNet, which is an adaptive routing algorithm for selecting an optimized network route using a mobile agent that simulates an ant. The AntNet-based hardware structure can be applied to a system-on-chip system. The original AntNet algorithm is adapted for hardware implementation. Performance of the modified algorithm of the invention was verified by comparing the modified algorithm with the original AntNet algorithm in a virtual network structure. The hardware structure of the invention is effective for AntNet-based routing.
